ELECTRIC FAN.

SPECIFICATION forming part of Letters Patent No. 660,551, dated October30, 1900.

Application filed May 8, 1900. Serial No. 15,987. (No model.)

[0 all ZU7'l/077b it away 0072007 77,.-

Be it known that I, JOHN TOM BESWIOK, a citizen of the United States,residing at New York city, borough of Brooklyn, county of Kings, Stateof New York, have invented certain new and useful Im provements inElectric Fans, of which the following is a specification.

My inventionrelates, first, to the containing'case and itssupporting-standard, by reason of which a great variety of positions maybe given to the fan; second, to the construction of the containing-case,whereby the cost of the motor may be materially reduced and the variousparts quickly removed for inspection and repair; third, to thecombination, with the containing-case, of detachable side platescarrying adjustable contact-brushes, whereby the interior of the casemay be easily inspected and the brushes adjusted or removed, and,fourth, to the construction of the guard for the rotating fan, by meansof which the fan is protected and the guard not easily bent or brokenwhen subjected to blows.

The accompanying drawings will serve to illustrate my invention.

Figure 1 is a View in perspective with one of the side plates of thecontaining-case removed. Fig. 2 is a view in perspective ofthecontaining-case with one bearing removed. Fig. 3 is a verticalsection. Fig. at is an'elevation and partial vertical section taken atright angles to that ofFig. 8. Fig. 5 is a partial transverse sectiontaken through the guard.

Similar letters of reference indicate like parts throughout the severalviews.

In the drawings, A represents the standard or base, the upper end of theinterior of which (best shown at Fig. is made concave at B and has aslot out through it at O.

D is the containing-case. Interposed between the contaiuing-case D andthe concave portion of the base A is a column E, which is convex at itslower portion F, where it comes in contact with the portion 13 of thecase A, and threaded over its upper cylindrical portion G. The column Eis connected to the containing-case D in any suitable manner.Surrounding the column E is a-ring H, having a depending portion I uponone side, which is located in the slot 0 of the standard A. Surroundingthe column E above the ring H is a second interiorly-threaded ring .I,pro vided with tangential arms K.

It will be observed that by reason of the arrangement described thecontaining-case D may be revolved horizontally around the top of thebase A and that it also may be inclined at an angle to the base A by themovement of the depending portion I of the ring H in the slot C of thestandard and when in this position may be revolved around the column E.By moving the threaded ring .I downward the angular position of thecontainingease D relative to the standard A may be fixed.

The containing-case D consists of a globular body L and the interiorconcave polepieces M. The containing-case D is provided with a fixedbearing N and removable bearing 0. The bearings N and 0 have cavities Pformed therein, which communicate through openings R with the exteriorof the bearings and through openings S with the interior of thebearings. The object of making the bearings with cavities as described,is for the purpose of introducing into them any semisolid lubricant ofthe character which when the bearings are slightly heated will be meltedand run through the openings S and lubricate the shaft T of the armatureU. The bearing N occupies a fixed position relative to thecontaining-case D, whereas the bearing 0 is mounted in a disk 0, whichfits into an opening provided for it in the case D. The. disk 0 is madeslightly larger than the diameter of the armature U, so that when thedisk 0 is removed the armature may be removed through the opening in thecase. This arrangement permits the easy removal of the armature forinspection and repair. The sides D of the containing-case D are formedas convex disks, which are secured to the case by means of suitablescrews. These sides are perforated at D and carry the contactbrushes V,which respectively bear upon the opposite sides of the commutator X ofthe armature U. The brushes V, behind which are the springs V, arecarried in rectangular tubes V having slotted heads. These tubes aresituated in insulated tubes carried in the side plates D. The insulatedtubes D are provided with bails D, which when the rectangular tubes Vare in position take into the slots in their heads. By pushing, in thetubes V tho bails I)"can be turned aside and the tubes V with theinclosed spring-pressed brushes, removed for the introduction oi newbrushes or for repairs.

Y represents the guard for the fan Z. The guard consists of the outerring Y, tubular spacing-columns Y inner ring Y interlaced wires Y,having the threaded ends Y and the securingnuts Y". It will be observedthat the ends of the interlaced wires are carried through thespacing-columns and secured by means of the nuts. The details of theconstruction of the guard is shown in Fig. 5. The object of thisconstruction is that all strains to which the guard is subjected will beresisted over the whole guard in a manner similar to that in whichstrains are resisted in a bicycle-wheel.

Having thus described my invention, I claim- 1. In an electric fan, thecombination of a containing-case, detachable side plates, andbrush-holders mounted in said side plates.

2. In an electric fan, the combination of a containing-case, detachableside plates, and removable brush holders mounted in said side plates.

3. In an electric fan, the combination of a containing-case, detachableside plates, and brush-holders, said brush-holders consisting of aninsulated tube carrying a pivoted bail, an inner removable tube with aslotted head, and a helical spring in said inner tube.

4. In an electric fan, the combination of a containing-case, a standardhaving a tubular vertical portion concave on its interior and slottedthrough one side near the top, a column provided with a convex headwhich conforms to the concavity of the standard and a cylindricalportion secu red to the containingcase.

5. In an electric fan the combination of a containing-case, a standardthe inner portion of the upper end of which is concave and slot.- ted atone side, and a column connected at one end to the containing-case andprovided at the other end with a convex head seated in the concavity ofthe standard and means for defining the position of the containingcaseand column, relative to the standard.

6. In an electric fan, the combination of a containing-case, a standardhaving a tubular vertical portion concave on its interior and slottedthrough one side near the top, a column having a convex head whichconforms to the concavity of the standard and a cylindrical threadedportion secured to the containing-case, a ring with a depending portionsurrounding the standard, and a second threaded ring located over thefirst-named ring.

7. In an electric fan, the combination of the containing-case, thestandard, the column E, ring II and threaded ring J.

In testimony whereof I aflix my signature in the presence of twowitnesses.

JOHN TOM BESWICK.
